3-6 Air Conditioning
Before using your vehicle's air conditioning, open the
windows to clear the vehicle of hot air. This reduces the
time it takes for your vehicle to cool down. Then keep
your windows closed for the air conditioner to work at
its best.
You can use MAX A/C with the temperature knob in
the blue area when it's really hot outside and you need
to cool the inside air quickly. MAX A/C lets in only a
little air from the outside.
If you first use MAX A/C, you can then use A/C with
the temperature knob in the blue area as soon as the
vehicle has cooled down, so outside air will be going
through your vehicle.
If your vehicle has rear air conditioning, setting it on LOW
may enhance the front air conditioning performance by
allowing trapped refrigerant in the rear lines to circulate.
The rear air conditioning system will only send cooled
air if the front system is on. It can still be used to
circulate air, even if the front system is off.
When the air conditioning, defrost or blend is on, you
may notice a slight increase or decrease in engine speed,
due to compressor operation. This is normal because the
system is designed to cycle the compressor on and off to
maintain the desired temperature.
Heating
On cold days, use the floor setting with the temperature
knob in the red area. Outside air will be brought in
through the floor ducts. The heater works best if you
keep your windows closed while using it.
If you use the optional engine coolant heater before
starting your engine, your heating system will produce
warmer air faster to heat the passenger compartment in
cold weather. See ªEngine Coolant Heaterº in the Index.
Defrosting
Use defrost to remove fog or ice from the windshield
quickly in extremely cold conditions. The temperature
knob should be in the red area and the fan control
toward high. The air conditioning compressor may
operate in this setting to dehumidify the air.
The blend setting is useful for cold weather with a large
number of passengers or very humid conditions to help
keep the windshield clear.
4-42 Trailer Wiring Harness
If you have the optional trailering package, your vehicle
will have an eight
-wire harness, including the center
high
-mounted stoplamp battery feed wire. The harness
is stored on the passenger's side of the vehicle near the
rear wheel well. This harness has a 30 amp battery
feed wire and no connector, and should be wired by
a qualified electrical technician. After choosing an
aftermarket trailer mating connector pair, have the
technician attach one connector to the eight
-wire trailer
harness and the other connector to the wiring harness on
the trailer. Be sure the wiring harness on the trailer is
taped or strapped to the trailer's frame rail and leave it
loose enough so the wiring doesn't bend or break, but
not so loose that it drags on the ground. The eight
-wire
harness must be routed out of your vehicle between the
rear door and the floor, with enough of the harness left
on both sides so that the trailer or the body won't pull it.
If you do not have the optional trailering package, your
vehicle will still have a trailering harness. The harness
is located near the passenger's side rear wheel well.
It consists of six wires that may be used by
after
-market trailer hitch installers.The technician can use the following color code chart
when connecting the wiring harness to your trailer.
Brown: Rear lamps.
Yellow: Left stoplamp and turn signal.
Dark Green: Right stoplamp and turn signal.
White (Heavy Gage): Ground.
Light Green: Back
-up lamps.
White (Light Gage): Center High
-Mounted
Stoplamp.
Blue: Auxiliary circuit (eight
-wire harness only).
Orange: Fused auxiliary (eight
-wire harness only).
Store the harness in its original place. Wrap the
harness together and tie it neatly so it won't
be damaged.
